Local or Global Image? The Role of Consumers' Local–Global Identity in Code-Switched Ad Effectiveness Among Monolinguals

Local and global brands alike have increasingly used code-switching to enhance advertising persuasion. Although this tactic is widely used, previous studies have focused on bilinguals but not monolinguals. Because of the emerging use of code-switching in advertisements in monolingual markets, more research efforts are required to understand its effectiveness and boundaries among monolinguals. This study investigated whether the consumers' local–global identity plays a moderating role in the effectiveness of code-switched advertisements among monolinguals. The consumers' local–global identity refers to the combination of local and global identities possessed by individuals that affect how they define themselves in relation to the social environment. Study 1 (manipulating consumers' local–global identity) demonstrated that the local–global identity moderated the effect of code-switched advertisements. The results indicated that the congruence between code-switching and the consumers' local–global identity enhanced persuasiveness, and that advertising involvement mediated this effect. Study 2 replicated the findings of Study 1 by using a local–global identity measure. These findings provide implications for branding and advertising strategies.
